81152-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81152-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,5 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81152-83:
(7*8)+(6*1)+(5*1)+(4*5)+(3*2)+(2*8)+(1*3)=112
112 % 10 = 2
So 81152-83-2 is a valid CAS Registry Number.
