1027052-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027052-37-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,0,5 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1027052-37:
(9*1)+(8*0)+(7*2)+(6*7)+(5*0)+(4*5)+(3*2)+(2*3)+(1*7)=104
104 % 10 = 4
So 1027052-37-4 is a valid CAS Registry Number.
