Check Digit Verification of cas no
The CAS Registry Mumber 3972-20-1 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 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3972-20:
(6*3)+(5*9)+(4*7)+(3*2)+(2*2)+(1*0)=101
101 % 10 = 1
So 3972-20-1 is a valid CAS Registry Number.
