77637-82-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77637-82-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,3 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77637-82:
(7*7)+(6*7)+(5*6)+(4*3)+(3*7)+(2*8)+(1*2)=172
172 % 10 = 2
So 77637-82-2 is a valid CAS Registry Number.
