636-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 636-88-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 636-88:
(5*6)+(4*3)+(3*6)+(2*8)+(1*8)=84
84 % 10 = 4
So 636-88-4 is a valid CAS Registry Number.
