127680-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127680-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,8 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 127680-64:
(8*1)+(7*2)+(6*7)+(5*6)+(4*8)+(3*0)+(2*6)+(1*4)=142
142 % 10 = 2
So 127680-64-2 is a valid CAS Registry Number.

THE REDUCTION OF N-(PHENYLSULFONYL)INDOLES WITH SODIUM CYANOBOROHYDRIDE IN TRIFLUOROACETIC ACID
Ketcha, Daniel M.,Lieurance, Brett A.
, p. 6833 - 6836 (2007/10/02)
The reduction of N-(phenylsulfonyl)indoles to the corresponding N-(phenylsulfonyl)indolines can be accomplished with good to excellent yields using cyanoborohydride (NaCNBH3) in trifluoroacetic acid (TFA).
