Check Digit Verification of cas no
The CAS Registry Mumber 71629-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,2 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71629-81:
(7*7)+(6*1)+(5*6)+(4*2)+(3*9)+(2*8)+(1*1)=137
137 % 10 = 7
So 71629-81-7 is a valid CAS Registry Number.
