Check Digit Verification of cas no

The CAS Registry Mumber 128434-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,3 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128434-65:
(8*1)+(7*2)+(6*8)+(5*4)+(4*3)+(3*4)+(2*6)+(1*5)=131
131 % 10 = 1
So 128434-65-1 is a valid CAS Registry Number.

Dephosphorylation of Cyano Diethyl Phosphates by Reduction with Lithium-Liquid Ammonia: An Efficient Method for Conversion of Carbonyl Compounds into Nitriles

Yoneda, Ryuji,Osaki, Takahiro,Harusawa, Shinya,Kurihara, Takushi

, p. 607 - 610 (2007/10/02)

Cyano diethyl phosphate derivatives of aromatic carbonyl compounds and α,β-unsaturated ketones were successively dephosphorylated by reduction with lithium in liquid ammonia followed by treatment with isoprene or alkyl halides to give β,γ-unsaturated nitriles or α-alkyl-β,γ-unsaturated nitriles in moderate to good yields.
