Check Digit Verification of cas no
The CAS Registry Mumber 122040-92-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122040-92:
(8*1)+(7*2)+(6*2)+(5*0)+(4*4)+(3*0)+(2*9)+(1*2)=70
70 % 10 = 0
So 122040-92-0 is a valid CAS Registry Number.
