Check Digit Verification of cas no

The CAS Registry Mumber 1231255-98-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,1,2,5 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1231255-98:
(9*1)+(8*2)+(7*3)+(6*1)+(5*2)+(4*5)+(3*5)+(2*9)+(1*8)=123
123 % 10 = 3
So 1231255-98-3 is a valid CAS Registry Number.

Li, Yibiao,Liu, Xiaohang,Jiang, Huanfeng,Feng, Zhenning

supporting information; experimental part, p. 3338 - 3341 (2010/07/10)

(Chemical Equation Presented) Side by side: Direct cis addition of bro-moalkynes 1 to various alkynes 2 was found to proceed in the presence of a PdII catalyst to give difunctionalized enyne products 3. The method is facile for the synthesis of bromo alkenynes. Further-more, an unusual mechanism is pro-posed.
