71862-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71862-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,6 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71862-20:
(7*7)+(6*1)+(5*8)+(4*6)+(3*2)+(2*2)+(1*0)=129
129 % 10 = 9
So 71862-20-9 is a valid CAS Registry Number.
