71851-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71851-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,5 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71851-65:
(7*7)+(6*1)+(5*8)+(4*5)+(3*1)+(2*6)+(1*5)=135
135 % 10 = 5
So 71851-65-5 is a valid CAS Registry Number.
