Check Digit Verification of cas no
The CAS Registry Mumber 147502-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,5,0 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 147502-37:
(8*1)+(7*4)+(6*7)+(5*5)+(4*0)+(3*2)+(2*3)+(1*7)=122
122 % 10 = 2
So 147502-37-2 is a valid CAS Registry Number.
