Check Digit Verification of cas no
The CAS Registry Mumber 3682-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,8 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3682-43:
(6*3)+(5*6)+(4*8)+(3*2)+(2*4)+(1*3)=97
97 % 10 = 7
So 3682-43-7 is a valid CAS Registry Number.
