Check Digit Verification of cas no
The CAS Registry Mumber 1629871-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,9,8,7 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1629871-65:
(9*1)+(8*6)+(7*2)+(6*9)+(5*8)+(4*7)+(3*1)+(2*6)+(1*5)=213
213 % 10 = 3
So 1629871-65-3 is a valid CAS Registry Number.
