Check Digit Verification of cas no

The CAS Registry Mumber 74916-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74916-75:
(7*7)+(6*4)+(5*9)+(4*1)+(3*6)+(2*7)+(1*5)=159
159 % 10 = 9
So 74916-75-9 is a valid CAS Registry Number.

Efficient Removal of N-Benzyloxycarbonyl Group by a 'Push-Pull' Mechanism using Thioanisole-Trifluoroacetic Acid, Examplified by a Synthesis of Met-Enkephalin

Kiso, Yoshiaki,Ukawa, Kazuko,Akita, Tadashi

, p. 101 - 102 (1980)

The N-benzyloxycarbonyl group can be smoothly cleaved under mild conditions, using thioanisole-trifluoroacetic acid, which can deprotect O-benzyltyrosine without the formation of O-to-C rearrangement products; this deblocking method was successfully applied to the synthesis of Met-enkephalin.
