78739-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78739-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,3 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78739-51:
(7*7)+(6*8)+(5*7)+(4*3)+(3*9)+(2*5)+(1*1)=182
182 % 10 = 2
So 78739-51-2 is a valid CAS Registry Number.
