Check Digit Verification of cas no
The CAS Registry Mumber 3971-35-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,7 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3971-35:
(6*3)+(5*9)+(4*7)+(3*1)+(2*3)+(1*5)=105
105 % 10 = 5
So 3971-35-5 is a valid CAS Registry Number.
