71918-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71918-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,1 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71918-12:
(7*7)+(6*1)+(5*9)+(4*1)+(3*8)+(2*1)+(1*2)=132
132 % 10 = 2
So 71918-12-2 is a valid CAS Registry Number.
