76461-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76461-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76461-97:
(7*7)+(6*6)+(5*4)+(4*6)+(3*1)+(2*9)+(1*7)=157
157 % 10 = 7
So 76461-97-7 is a valid CAS Registry Number.
