74152-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74152-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,5 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74152-90:
(7*7)+(6*4)+(5*1)+(4*5)+(3*2)+(2*9)+(1*0)=122
122 % 10 = 2
So 74152-90-2 is a valid CAS Registry Number.
