122238-01-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122238-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,2,3 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 122238-01:
(8*1)+(7*2)+(6*2)+(5*2)+(4*3)+(3*8)+(2*0)+(1*1)=81
81 % 10 = 1
So 122238-01-1 is a valid CAS Registry Number.
