Check Digit Verification of cas no
The CAS Registry Mumber 19956-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,5 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 19956-45:
(7*1)+(6*9)+(5*9)+(4*5)+(3*6)+(2*4)+(1*5)=157
157 % 10 = 7
So 19956-45-7 is a valid CAS Registry Number.
