Check Digit Verification of cas no
The CAS Registry Mumber 150869-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,8,6 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 150869-53:
(8*1)+(7*5)+(6*0)+(5*8)+(4*6)+(3*9)+(2*5)+(1*3)=147
147 % 10 = 7
So 150869-53-7 is a valid CAS Registry Number.
