77244-98-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77244-98-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,4 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77244-98:
(7*7)+(6*7)+(5*2)+(4*4)+(3*4)+(2*9)+(1*8)=155
155 % 10 = 5
So 77244-98-5 is a valid CAS Registry Number.
