Check Digit Verification of cas no
The CAS Registry Mumber 42211-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,1 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42211-33:
(7*4)+(6*2)+(5*2)+(4*1)+(3*1)+(2*3)+(1*3)=66
66 % 10 = 6
So 42211-33-6 is a valid CAS Registry Number.
