Check Digit Verification of cas no

The CAS Registry Mumber 1386875-45-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,6,8,7 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1386875-45:
(9*1)+(8*3)+(7*8)+(6*6)+(5*8)+(4*7)+(3*5)+(2*4)+(1*5)=221
221 % 10 = 1
So 1386875-45-1 is a valid CAS Registry Number.

Copper-catalyzed aerobic methyl/methylene oxygenation and C-H formylation with a DABCO-DMSO system for the synthesis of carbonyl indoles and pyrroles

Wang, Yi-Feng,Zhang, Feng-Lian,Chiba, Shunsuke

supporting information; experimental part, p. 1526 - 1534 (2012/06/18)

Copper-catalyzed aerobic methyl/methylene oxygenation of substituted indoles and pyrroles was developed using 1,4-diazabicyclo[2.2.2]octane (DABCO) as an additive in dimethyl sulfoxide (DMSO). Similar aerobic catalytic conditions could also be utilized for direct C-H formylation of C(3) on indoles and C(2) on pyrroles.
