1137183-07-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1137183-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,7,1,8 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1137183-07:
(9*1)+(8*1)+(7*3)+(6*7)+(5*1)+(4*8)+(3*3)+(2*0)+(1*7)=133
133 % 10 = 3
So 1137183-07-3 is a valid CAS Registry Number.
