82957-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82957-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,5 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82957-87:
(7*8)+(6*2)+(5*9)+(4*5)+(3*7)+(2*8)+(1*7)=177
177 % 10 = 7
So 82957-87-7 is a valid CAS Registry Number.
