1187028-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187028-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,0,2 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1187028-21:
(9*1)+(8*1)+(7*8)+(6*7)+(5*0)+(4*2)+(3*8)+(2*2)+(1*1)=152
152 % 10 = 2
So 1187028-21-2 is a valid CAS Registry Number.

Intramolecular aminocyanation of alkenes by N-CN bond cleavage
Pan, Zhongda,Pound, Sarah M.,Rondla, Naveen R.,Douglas, Christopher J.
, p. 5170 - 5174 (2014/05/20)
A metal-free, Lewis acid promoted intramolecular aminocyanation of alkenes was developed. B(C6F5)3 activates N-sulfonyl cyanamides, thus leading to a formal cleavage of the N-CN bonds in conjunction with vicinal addition o
