Check Digit Verification of cas no
The CAS Registry Mumber 136403-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136403-38:
(8*1)+(7*3)+(6*6)+(5*4)+(4*0)+(3*3)+(2*3)+(1*8)=108
108 % 10 = 8
So 136403-38-8 is a valid CAS Registry Number.
