Check Digit Verification of cas no
The CAS Registry Mumber 73837-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,3 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73837-65:
(7*7)+(6*3)+(5*8)+(4*3)+(3*7)+(2*6)+(1*5)=157
157 % 10 = 7
So 73837-65-7 is a valid CAS Registry Number.
