174787-29-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174787-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,7,8 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 174787-29:
(8*1)+(7*7)+(6*4)+(5*7)+(4*8)+(3*7)+(2*2)+(1*9)=182
182 % 10 = 2
So 174787-29-2 is a valid CAS Registry Number.
