67739-37-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67739-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,3 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67739-37:
(7*6)+(6*7)+(5*7)+(4*3)+(3*9)+(2*3)+(1*7)=171
171 % 10 = 1
So 67739-37-1 is a valid CAS Registry Number.
