Check Digit Verification of cas no
The CAS Registry Mumber 21312-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,1 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21312-85:
(7*2)+(6*1)+(5*3)+(4*1)+(3*2)+(2*8)+(1*5)=66
66 % 10 = 6
So 21312-85-6 is a valid CAS Registry Number.
