Check Digit Verification of cas no
The CAS Registry Mumber 134278-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,7 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134278-08:
(8*1)+(7*3)+(6*4)+(5*2)+(4*7)+(3*8)+(2*0)+(1*8)=123
123 % 10 = 3
So 134278-08-3 is a valid CAS Registry Number.
