141858-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141858-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,5 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 141858-98:
(8*1)+(7*4)+(6*1)+(5*8)+(4*5)+(3*8)+(2*9)+(1*8)=152
152 % 10 = 2
So 141858-98-2 is a valid CAS Registry Number.

, p. 743 - 756 (2007/10/02)
An enantiocontrolled route to the common C11-17 segment (2) of mycinamicins III (1a) and IV (1b) has been developed starting from the chiral α-hydroxyacetylene (6) obtained from (E)-4-benzyloxybut-2-en-1-ol (3).
