Check Digit Verification of cas no
The CAS Registry Mumber 156816-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,1 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156816-78:
(8*1)+(7*5)+(6*6)+(5*8)+(4*1)+(3*6)+(2*7)+(1*8)=163
163 % 10 = 3
So 156816-78-3 is a valid CAS Registry Number.
