1214267-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1214267-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,4,2,6 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1214267-20:
(9*1)+(8*2)+(7*1)+(6*4)+(5*2)+(4*6)+(3*7)+(2*2)+(1*0)=115
115 % 10 = 5
So 1214267-20-5 is a valid CAS Registry Number.
