Check Digit Verification of cas no
The CAS Registry Mumber 134079-92-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,7 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134079-92:
(8*1)+(7*3)+(6*4)+(5*0)+(4*7)+(3*9)+(2*9)+(1*2)=128
128 % 10 = 8
So 134079-92-8 is a valid CAS Registry Number.
