Check Digit Verification of cas no

The CAS Registry Mumber 128315-94-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,1 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128315-94:
(8*1)+(7*2)+(6*8)+(5*3)+(4*1)+(3*5)+(2*9)+(1*4)=126
126 % 10 = 6
So 128315-94-6 is a valid CAS Registry Number.

ORGANOBORON COMPOUNDS. CDIII. IODINATION OF ATE COMPLEXES OF 1-BORAADAMANTANE

Mikhailov, B. M.,Gurskii, M. E.,Pershin, D. G.

, p. 19 - 28 (2007/10/02)

The complex of 1-boraadamantane with tetrahydrofuran (1) reacts with iodine in the presence of lithium methylate or methyllithium to produce 3-methoxy- (III) and 3-methyl-7-iodomethyl-3-borabicyclononane (X), respectively.Further iodination of III in the presence of lithium methylate proceeds in a complicated manner due to replacement of iodine by the methoxy group in the starting compound.The high reactivity of the halogen in III permitted a one-pot synthesis of 3-methoxy-7-methoxymethyl-3-borabicyclononane from I.Iodination of lithium 1-isopropenyl-1-boraadamantanate leads, after methanolysis, to 3-methoxy-7-isobutenyl-3-borabicyclononane.The latter compound was converted to 7-isobutenyl-3-methyl-3-borabicyclononane on treatment with MeMgI.
