1338356-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338356-23-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,5 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1338356-23:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*5)+(3*6)+(2*2)+(1*3)=162
162 % 10 = 2
So 1338356-23-2 is a valid CAS Registry Number.
