149772-23-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149772-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,7,7 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149772-23:
(8*1)+(7*4)+(6*9)+(5*7)+(4*7)+(3*2)+(2*2)+(1*3)=166
166 % 10 = 6
So 149772-23-6 is a valid CAS Registry Number.
