Check Digit Verification of cas no
The CAS Registry Mumber 170808-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,8,0 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 170808-37:
(8*1)+(7*7)+(6*0)+(5*8)+(4*0)+(3*8)+(2*3)+(1*7)=134
134 % 10 = 4
So 170808-37-4 is a valid CAS Registry Number.
