Check Digit Verification of cas no
The CAS Registry Mumber 172788-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,8 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 172788-94:
(8*1)+(7*7)+(6*2)+(5*7)+(4*8)+(3*8)+(2*9)+(1*4)=182
182 % 10 = 2
So 172788-94-2 is a valid CAS Registry Number.
