77855-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77855-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,5 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77855-52:
(7*7)+(6*7)+(5*8)+(4*5)+(3*5)+(2*5)+(1*2)=178
178 % 10 = 8
So 77855-52-8 is a valid CAS Registry Number.

Harada, Kaoru,Munegumi, Toratane,Nomoto, Shinya
, p. 111 - 114 (2007/10/02)
Asymmetric catalytic hydrogenations of three kinds of chiral pyruvamides were carried out using palladium on charcoal as a catalyst to give lactamides with diastereomeric ratios ranging from 76:24 to 98:2.
