142274-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142274-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,7 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142274-35:
(8*1)+(7*4)+(6*2)+(5*2)+(4*7)+(3*4)+(2*3)+(1*5)=109
109 % 10 = 9
So 142274-35-9 is a valid CAS Registry Number.
