1158722-37-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1158722-37-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,7,2 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1158722-37:
(9*1)+(8*1)+(7*5)+(6*8)+(5*7)+(4*2)+(3*2)+(2*3)+(1*7)=162
162 % 10 = 2
So 1158722-37-2 is a valid CAS Registry Number.
