Check Digit Verification of cas no
The CAS Registry Mumber 134704-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,0 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134704-07:
(8*1)+(7*3)+(6*4)+(5*7)+(4*0)+(3*4)+(2*0)+(1*7)=107
107 % 10 = 7
So 134704-07-7 is a valid CAS Registry Number.
