Check Digit Verification of cas no
The CAS Registry Mumber 139021-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139021-90:
(8*1)+(7*3)+(6*9)+(5*0)+(4*2)+(3*1)+(2*9)+(1*0)=112
112 % 10 = 2
So 139021-90-2 is a valid CAS Registry Number.
