Check Digit Verification of cas no
The CAS Registry Mumber 212331-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,3,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 212331-33:
(8*2)+(7*1)+(6*2)+(5*3)+(4*3)+(3*1)+(2*3)+(1*3)=74
74 % 10 = 4
So 212331-33-4 is a valid CAS Registry Number.
