651729-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 651729-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,1,7,2 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 651729-20:
(8*6)+(7*5)+(6*1)+(5*7)+(4*2)+(3*9)+(2*2)+(1*0)=163
163 % 10 = 3
So 651729-20-3 is a valid CAS Registry Number.
