Check Digit Verification of cas no
The CAS Registry Mumber 352200-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,2,0 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 352200-67:
(8*3)+(7*5)+(6*2)+(5*2)+(4*0)+(3*0)+(2*6)+(1*7)=100
100 % 10 = 0
So 352200-67-0 is a valid CAS Registry Number.
