Check Digit Verification of cas no
The CAS Registry Mumber 33689-83-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,8 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33689-83:
(7*3)+(6*3)+(5*6)+(4*8)+(3*9)+(2*8)+(1*3)=147
147 % 10 = 7
So 33689-83-7 is a valid CAS Registry Number.
