Check Digit Verification of cas no
The CAS Registry Mumber 6372-96-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6372-96:
(6*6)+(5*3)+(4*7)+(3*2)+(2*9)+(1*6)=109
109 % 10 = 9
So 6372-96-9 is a valid CAS Registry Number.
