Check Digit Verification of cas no
The CAS Registry Mumber 340157-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,1,5 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 340157-85:
(8*3)+(7*4)+(6*0)+(5*1)+(4*5)+(3*7)+(2*8)+(1*5)=119
119 % 10 = 9
So 340157-85-9 is a valid CAS Registry Number.
