1422186-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422186-22-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,1,8 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1422186-22:
(9*1)+(8*4)+(7*2)+(6*2)+(5*1)+(4*8)+(3*6)+(2*2)+(1*2)=128
128 % 10 = 8
So 1422186-22-8 is a valid CAS Registry Number.
