94137-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94137-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,3 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94137-50:
(7*9)+(6*4)+(5*1)+(4*3)+(3*7)+(2*5)+(1*0)=135
135 % 10 = 5
So 94137-50-5 is a valid CAS Registry Number.
