99987-95-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99987-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,8 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99987-95:
(7*9)+(6*9)+(5*9)+(4*8)+(3*7)+(2*9)+(1*5)=238
238 % 10 = 8
So 99987-95-8 is a valid CAS Registry Number.
