142274-26-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142274-26-8 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, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142274-26:
(8*1)+(7*4)+(6*2)+(5*2)+(4*7)+(3*4)+(2*2)+(1*6)=108
108 % 10 = 8
So 142274-26-8 is a valid CAS Registry Number.
