1391581-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1391581-97-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,5,8 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1391581-97:
(9*1)+(8*3)+(7*9)+(6*1)+(5*5)+(4*8)+(3*1)+(2*9)+(1*7)=187
187 % 10 = 7
So 1391581-97-7 is a valid CAS Registry Number.

An efficient and facile synthesis of N-Cbz-β-aminoalkanesulfonamides
Meng, Fanhua,Chen, Ning,Xu, Jiaxi
, p. 2548 - 2553 (2013/06/27)
An efficient method for the synthesis of N-Cbz-β- aminoalkanesulfonamides was described. N-Cbz-β-aminoalkanesulfona-mides were readily prepared in good yields from a variety of amino alcohols, including optically active ones, via N-Cbz protection with ben
