6937-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6937-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6937-67:
(6*6)+(5*9)+(4*3)+(3*7)+(2*6)+(1*7)=133
133 % 10 = 3
So 6937-67-3 is a valid CAS Registry Number.
