651022-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 651022-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,1,0,2 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 651022-59:
(8*6)+(7*5)+(6*1)+(5*0)+(4*2)+(3*2)+(2*5)+(1*9)=122
122 % 10 = 2
So 651022-59-2 is a valid CAS Registry Number.
