77244-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77244-90-7 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 77244-90:
(7*7)+(6*7)+(5*2)+(4*4)+(3*4)+(2*9)+(1*0)=147
147 % 10 = 7
So 77244-90-7 is a valid CAS Registry Number.
