Check Digit Verification of cas no
The CAS Registry Mumber 678173-42-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,7 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 678173-42:
(8*6)+(7*7)+(6*8)+(5*1)+(4*7)+(3*3)+(2*4)+(1*2)=197
197 % 10 = 7
So 678173-42-7 is a valid CAS Registry Number.
