177326-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 177326-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,3,2 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 177326-23:
(8*1)+(7*7)+(6*7)+(5*3)+(4*2)+(3*6)+(2*2)+(1*3)=147
147 % 10 = 7
So 177326-23-7 is a valid CAS Registry Number.
