Check Digit Verification of cas no
The CAS Registry Mumber 106367-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,3,6 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 106367-50:
(8*1)+(7*0)+(6*6)+(5*3)+(4*6)+(3*7)+(2*5)+(1*0)=114
114 % 10 = 4
So 106367-50-4 is a valid CAS Registry Number.
