Check Digit Verification of cas no
The CAS Registry Mumber 150931-15-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,9,3 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 150931-15:
(8*1)+(7*5)+(6*0)+(5*9)+(4*3)+(3*1)+(2*1)+(1*5)=110
110 % 10 = 0
So 150931-15-0 is a valid CAS Registry Number.
