Check Digit Verification of cas no

The CAS Registry Mumber 1287302-50-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,3,0 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1287302-50:
(9*1)+(8*2)+(7*8)+(6*7)+(5*3)+(4*0)+(3*2)+(2*5)+(1*0)=154
154 % 10 = 4
So 1287302-50-4 is a valid CAS Registry Number.

Double duty for cyanogen bromide in a cascade synthesis of cyanoepoxides

Li, Zhou,Gevorgyan, Vladimir

, p. 2808 - 2810 (2011)

An unprecedented reaction mode of cyanogen bromide has been discovered. Under basic conditions, cyanogen bromide acts as an equivalent of both Br + and CN- to convert enolizable ketones into the corresponding cyanoepoxides in good yields. This unique reaction mode provides new, one-pot access to densely substituted cyanoepoxides from easily available ketones (see scheme). Copyright
