Check Digit Verification of cas no
The CAS Registry Mumber 889652-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,6,5 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 889652-31:
(8*8)+(7*8)+(6*9)+(5*6)+(4*5)+(3*2)+(2*3)+(1*1)=237
237 % 10 = 7
So 889652-31-7 is a valid CAS Registry Number.
