15542-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15542-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,4 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15542-61:
(7*1)+(6*5)+(5*5)+(4*4)+(3*2)+(2*6)+(1*1)=97
97 % 10 = 7
So 15542-61-7 is a valid CAS Registry Number.
