1258948-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258948-42-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,9,4 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1258948-42:
(9*1)+(8*2)+(7*5)+(6*8)+(5*9)+(4*4)+(3*8)+(2*4)+(1*2)=203
203 % 10 = 3
So 1258948-42-3 is a valid CAS Registry Number.
