1572044-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1572044-91-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,2,0,4 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1572044-91:
(9*1)+(8*5)+(7*7)+(6*2)+(5*0)+(4*4)+(3*4)+(2*9)+(1*1)=157
157 % 10 = 7
So 1572044-91-7 is a valid CAS Registry Number.
