77831-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77831-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,3 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77831-53:
(7*7)+(6*7)+(5*8)+(4*3)+(3*1)+(2*5)+(1*3)=159
159 % 10 = 9
So 77831-53-9 is a valid CAS Registry Number.
