77270-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77270-63-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,7 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77270-63:
(7*7)+(6*7)+(5*2)+(4*7)+(3*0)+(2*6)+(1*3)=144
144 % 10 = 4
So 77270-63-4 is a valid CAS Registry Number.
