98776-95-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98776-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,7 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98776-95:
(7*9)+(6*8)+(5*7)+(4*7)+(3*6)+(2*9)+(1*5)=215
215 % 10 = 5
So 98776-95-5 is a valid CAS Registry Number.
