77556-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77556-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,5 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77556-32:
(7*7)+(6*7)+(5*5)+(4*5)+(3*6)+(2*3)+(1*2)=162
162 % 10 = 2
So 77556-32-2 is a valid CAS Registry Number.
