70152-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70152-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,5 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70152-44:
(7*7)+(6*0)+(5*1)+(4*5)+(3*2)+(2*4)+(1*4)=92
92 % 10 = 2
So 70152-44-2 is a valid CAS Registry Number.
