1137672-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1137672-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,7,6,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1137672-91:
(9*1)+(8*1)+(7*3)+(6*7)+(5*6)+(4*7)+(3*2)+(2*9)+(1*1)=163
163 % 10 = 3
So 1137672-91-3 is a valid CAS Registry Number.
