Check Digit Verification of cas no
The CAS Registry Mumber 3682-47-1 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 3682-47:
(6*3)+(5*6)+(4*8)+(3*2)+(2*4)+(1*7)=101
101 % 10 = 1
So 3682-47-1 is a valid CAS Registry Number.
