947251-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 947251-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,2,5 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 947251-88:
(8*9)+(7*4)+(6*7)+(5*2)+(4*5)+(3*1)+(2*8)+(1*8)=199
199 % 10 = 9
So 947251-88-9 is a valid CAS Registry Number.
