137934-94-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137934-94-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,3 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137934-94:
(8*1)+(7*3)+(6*7)+(5*9)+(4*3)+(3*4)+(2*9)+(1*4)=162
162 % 10 = 2
So 137934-94-2 is a valid CAS Registry Number.
