Check Digit Verification of cas no
The CAS Registry Mumber 1219113-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,1,1 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1219113-18:
(9*1)+(8*2)+(7*1)+(6*9)+(5*1)+(4*1)+(3*3)+(2*1)+(1*8)=114
114 % 10 = 4
So 1219113-18-4 is a valid CAS Registry Number.
