Check Digit Verification of cas no
The CAS Registry Mumber 148719-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,7,1 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 148719-91:
(8*1)+(7*4)+(6*8)+(5*7)+(4*1)+(3*9)+(2*9)+(1*1)=169
169 % 10 = 9
So 148719-91-9 is a valid CAS Registry Number.
