Check Digit Verification of cas no
The CAS Registry Mumber 3861-73-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,6 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3861-73:
(6*3)+(5*8)+(4*6)+(3*1)+(2*7)+(1*3)=102
102 % 10 = 2
So 3861-73-2 is a valid CAS Registry Number.
