1374153-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1374153-23-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,1,5 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1374153-23:
(9*1)+(8*3)+(7*7)+(6*4)+(5*1)+(4*5)+(3*3)+(2*2)+(1*3)=147
147 % 10 = 7
So 1374153-23-7 is a valid CAS Registry Number.
