Check Digit Verification of cas no
The CAS Registry Mumber 1220911-01-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,9,1 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1220911-01:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*1)+(3*1)+(2*0)+(1*1)=92
92 % 10 = 2
So 1220911-01-2 is a valid CAS Registry Number.
