Check Digit Verification of cas no
The CAS Registry Mumber 623174-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,1,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 623174-52:
(8*6)+(7*2)+(6*3)+(5*1)+(4*7)+(3*4)+(2*5)+(1*2)=137
137 % 10 = 7
So 623174-52-7 is a valid CAS Registry Number.
