Check Digit Verification of cas no
The CAS Registry Mumber 156459-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,4,5 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156459-19:
(8*1)+(7*5)+(6*6)+(5*4)+(4*5)+(3*9)+(2*1)+(1*9)=157
157 % 10 = 7
So 156459-19-7 is a valid CAS Registry Number.
