69094-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69094-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,9 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 69094-37:
(7*6)+(6*9)+(5*0)+(4*9)+(3*4)+(2*3)+(1*7)=157
157 % 10 = 7
So 69094-37-7 is a valid CAS Registry Number.
