Check Digit Verification of cas no
The CAS Registry Mumber 167868-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,8,6 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 167868-39:
(8*1)+(7*6)+(6*7)+(5*8)+(4*6)+(3*8)+(2*3)+(1*9)=195
195 % 10 = 5
So 167868-39-5 is a valid CAS Registry Number.
