Check Digit Verification of cas no
The CAS Registry Mumber 134671-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,7 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134671-47:
(8*1)+(7*3)+(6*4)+(5*6)+(4*7)+(3*1)+(2*4)+(1*7)=129
129 % 10 = 9
So 134671-47-9 is a valid CAS Registry Number.
