Check Digit Verification of cas no
The CAS Registry Mumber 1082287-31-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,2,2,8 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1082287-31:
(9*1)+(8*0)+(7*8)+(6*2)+(5*2)+(4*8)+(3*7)+(2*3)+(1*1)=147
147 % 10 = 7
So 1082287-31-7 is a valid CAS Registry Number.
