102971-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102971-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 102971-20:
(8*1)+(7*0)+(6*2)+(5*9)+(4*7)+(3*1)+(2*2)+(1*0)=100
100 % 10 = 0
So 102971-20-0 is a valid CAS Registry Number.
