Check Digit Verification of cas no
The CAS Registry Mumber 99131-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,3 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99131-26:
(7*9)+(6*9)+(5*1)+(4*3)+(3*1)+(2*2)+(1*6)=147
147 % 10 = 7
So 99131-26-7 is a valid CAS Registry Number.
