Check Digit Verification of cas no
The CAS Registry Mumber 1422007-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,0,0 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1422007-52:
(9*1)+(8*4)+(7*2)+(6*2)+(5*0)+(4*0)+(3*7)+(2*5)+(1*2)=100
100 % 10 = 0
So 1422007-52-0 is a valid CAS Registry Number.
