Check Digit Verification of cas no

The CAS Registry Mumber 1173936-61-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,3 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1173936-61:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*3)+(3*6)+(2*6)+(1*1)=172
172 % 10 = 2
So 1173936-61-2 is a valid CAS Registry Number.

Catalytic one-pot synthesis of trisubstituted allenes from terminal alkynes and ketones

Liu, Qi,Tang, Xinjun,Cai, Yujuan,Ma, Shengming

, p. 5174 - 5177 (2017)

An efficient one-pot synthesis of trisubstituted allenes from readily available terminal alkynes and ketones is realized. A wide range of trisubstituted allenes may be synthesized efficiently via this method. Preliminary mechanistic studies revealed that CuI and Ti(OEt)4 are in charge of the formation of propargylic amine, while ZnBr2 is responsible for the transformation from propargylic amine to allene.
