93033-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93033-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,3 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 93033-97:
(7*9)+(6*3)+(5*0)+(4*3)+(3*3)+(2*9)+(1*7)=127
127 % 10 = 7
So 93033-97-7 is a valid CAS Registry Number.

(Z)-Narceine enol lactone (10) is thermodinamically less stable than its geometric isomer 11, and solvolyses faster in methanol to provide keto ester 9. In the less hindered hydrastine series, however, the order is reversed, and it is the E isomer 4 which
