Check Digit Verification of cas no
The CAS Registry Mumber 105052-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,5 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 105052-38:
(8*1)+(7*0)+(6*5)+(5*0)+(4*5)+(3*2)+(2*3)+(1*8)=78
78 % 10 = 8
So 105052-38-8 is a valid CAS Registry Number.
