77726-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77726-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,2 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77726-50:
(7*7)+(6*7)+(5*7)+(4*2)+(3*6)+(2*5)+(1*0)=162
162 % 10 = 2
So 77726-50-2 is a valid CAS Registry Number.
