Check Digit Verification of cas no
The CAS Registry Mumber 830346-46-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,0,3,4 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 830346-46:
(8*8)+(7*3)+(6*0)+(5*3)+(4*4)+(3*6)+(2*4)+(1*6)=148
148 % 10 = 8
So 830346-46-8 is a valid CAS Registry Number.
