1422181-83-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422181-83-6 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 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1422181-83:
(9*1)+(8*4)+(7*2)+(6*2)+(5*1)+(4*8)+(3*1)+(2*8)+(1*3)=126
126 % 10 = 6
So 1422181-83-6 is a valid CAS Registry Number.
