174873-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174873-76-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,8,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 174873-76:
(8*1)+(7*7)+(6*4)+(5*8)+(4*7)+(3*3)+(2*7)+(1*6)=178
178 % 10 = 8
So 174873-76-8 is a valid CAS Registry Number.
