90545-58-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90545-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,4 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90545-58:
(7*9)+(6*0)+(5*5)+(4*4)+(3*5)+(2*5)+(1*8)=137
137 % 10 = 7
So 90545-58-7 is a valid CAS Registry Number.

PREPARATION OF CHIRAL 5-DEAZAFLAVIN DERIVATIVES AND THEIR ASYMMETRIC REDUCTION OF ETHYL BENZOYLFORMATE
Tanaka, Kiyoshi,Okada, Tomoya,Yoneda, Fumio
, p. 1741 - 1742 (2007/10/02)
1,5-Dihydro-5-deazaflavin derivatives possessing a chiral substituent at N(3) position were synthesized, with which moderate asymmetric induction was observed in the reduction of ethyl benzoilformate.
