Check Digit Verification of cas no
The CAS Registry Mumber 151919-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,9,1 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151919-83:
(8*1)+(7*5)+(6*1)+(5*9)+(4*1)+(3*9)+(2*8)+(1*3)=144
144 % 10 = 4
So 151919-83-4 is a valid CAS Registry Number.
