1422157-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422157-06-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,1,5 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1422157-06:
(9*1)+(8*4)+(7*2)+(6*2)+(5*1)+(4*5)+(3*7)+(2*0)+(1*6)=119
119 % 10 = 9
So 1422157-06-9 is a valid CAS Registry Number.
