Check Digit Verification of cas no
The CAS Registry Mumber 1219020-12-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,0,2 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1219020-12:
(9*1)+(8*2)+(7*1)+(6*9)+(5*0)+(4*2)+(3*0)+(2*1)+(1*2)=98
98 % 10 = 8
So 1219020-12-8 is a valid CAS Registry Number.
