33974-38-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33974-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,7 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 33974-38:
(7*3)+(6*3)+(5*9)+(4*7)+(3*4)+(2*3)+(1*8)=138
138 % 10 = 8
So 33974-38-8 is a valid CAS Registry Number.
